Using a hand-guided scanner with color display, move the scanner horizontally and vertically across a measured template grid and analyze the scans immediately on the X-Scan display. With the aid of the PSA 100 field-rugged monitor, you can show objects in 3D images for on-the-spot interpretation, making it easy to find and mark potential drilling locations, limiting damage caused by hitting rebars, pipes or post-tension cables. Hilti says the device helps contractors do their own field scans, decreasing the need to hire specialists.
